- ASH-CONVEYEB SYSTEM.

Application filed September 5, 1922. Serial No. 586,162.

and in which the wearin arts ma be easil removed for renewal or the like whenever necessary;

Another object of my invention is to provide ash intakes in said lineinto which the ash may be charged from the furnace and through which connection a steam jet or the like may be passed for the purpose-of boosting the velocity of the ash thereat Another object of my invention is to provide an intake booster as, above described, in

which th wear-back portion thereof may be easily removed from the line without disassembling or removing any other part of the fitting.

Another object of my invention isto provide an intake booster of such a shape and form that the ash admitted thereinto at one nd will be directed. into the path of the jetof steam, air, or the like, and be :discharged at the opposite end through an opening whose axis is in alignment with the axis of the jet, and in which fitting there is provided anotheror main ,ash intake having a removable cover and into which the ashes may be admitted from the bo-iler'directly into the pathof, the jet in alignmentiwith the jet and the outlet. 7 V Many other objectsandadvantages of the construction herein shown and described will be obviousto those ,skilledin the art from' the disclosures herein given. To this end my invention consists the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed 'out in ,the

.In the drawings, wherein I have illustrated the preferred embodiment of my iiivention, 1 represents the boilers, 'WhlOl'lflIlfiy be of any construction or type whatsoever and from which the ashes are to be with:

drawn and conveyed away. 2 represents a portion of theash conveyer lyingsubstantiallyin a horizontalplane below, the level of the ash doors'of the boilers, this con veyer line inclined upwardly vat'on'e end beyond the line of the boilers as at 3, and

terminating in an impact box or target 1,.-

at its upper end and from which the ashes may be discharged into any convenient receptacle or'onto the ground, as desired. In

the conveyor line, adjacent each of the boilers is an ash intake 5, into which the ashes from the boiler may be discharged} and carried through the conveyer line toflthe target 4, each of the intake fittings preferably having a removable cover 6 suitably arranged thereon.

At the bend in the line is a booster inemlxerv 7, having a st'eam jetinlet 8 leading thereto the same controlled by any suitable valve 9,

to boost th evelocity of the ashes *at-this pointand to move them directly'to the target box 4, at increased velocity. By placinga45 booster fitting at this point, as shown, there is a saving-over the number of fittingsrequired and also in amount of'steam necessary conveying line wherein the portion .3 of the, line is eXte-n'dedverticall'y and thence horizontally to dischargeiinto the: target box.

j forth conveying, over the usualtype of.

An sake. beg ar sang 9 maybe a r-j ranged at any one of th ash intakes-intermediate the ends of the line, as shown, and

. by means ofwhich the velocit'y of the ashes passing therethrough may be increased to above that just preceding the point of entry of ashes thereto, and in which the ashes discharged directly from the boiler will be conveyedby theboosting jets This booster intake fittingcomprises two parts 10 and 11, of any desired Inetal that of the part ll being either of the same hardness as that of the part 10, or of afgreater hardness. as desired, and removably secured together by means or" detachable bolts 12 so as to form a. casing. Both of th 'end's of the fitting are flanged, as at 13. and and each of the fianges are provided with elongated bolt holes 15 therethrough for detachably connecting the fitting to the adjacent line fittings.

At one end of the fitting, the part 10 is provided with a pairv of inlets l6 and 17.

the former being the inlet nozzle for the jet of steam, air or the like, and the latter being for the admission of ash or other material being conveyed through the section, these inlets being laterally spaced apart, and opening into a common chamber. Theinner face 18 of the wear part 11 is preterably fiat or straight, as most clearlyshown in -Figsf6 and 7. The jet inlet nozzle 16 is preferably screwed into a threaded plug, (see Fig. 4) set in wl1 en the parts are cast. because as the part 10 is of a very hard inaterial it would be rather difficult to thread the same and securethe nozzle thereto. after casting. The plugma-y be or softer metal easily threaded.

At the opposite end of thefitting and in axial alignment with the steam jet inlet is an outlet port 19 formed jointly by the members 10 and 11, as shown, I The inner surface of the wear back memberll is inclined from the intake to the outlet so that the material admitted through the inlet port will be deflected directly into the jet coming through the jet inlet, the same carrying the charge outwardly through the discharge outlet- 19. T he jet tends to create a vacuum or suction which willdraw the ash impelled through the inlet l7,'and gets back of said ,ash and pushes, forces or shoots the ash outwardly through said outlet. 7

The wear-back member at the'point of greatest wear is straight, as before mene tionechan'd is preferably thickened in cross section so that-thelongevity of the parts is greatly increased. The meeting edges or sides of the wearback member or body part respectively arepreferably flanged and in "each ot'tliese meeting edges is formed a series of cooperating stepped portions,

shoulders or tongue and grooves into which a pack ng material may be inserted when the two parts are assembled. Whenever it is desired to renew the wear-back member after the; booster is assembled in the conveyer line, the boltsl2 are loosened and said wear-back. member may be removed without disturbing the rest of the line.

Intermediate the ends of the fitting in very easily removed when desired. The

openlng 2O permits the discharge or the ashes directly into the path of the steam A jet and the same blows said ashes through the outlet 19 and through the line.

By the use of my improved booster intake fitting the number of fittings the line may be materially reduced, inasmuch as in this case the ash intake and booster fitting are combined in one, thus greatly reducing the cost of the installation.

In Fig. 8 I have shown a type of fitting that'may be used at the end of the line,

thesanie being open to permit the admis sion of air, and in this-particular one it is shown with an 'ash or material inlet. Referring to Fig. 8, a nozzle 28 18 carried by the support 26 which may be arranged on a spider 27, the same supporting and Contering the nozzle. Obviously, the nozzle may be connected with a steam line or the like in any suitable manner. The inlet end, as shown, is slightly flared. here desired,

however, a standard fitting similar to the fittings 5 may be employed and a flared end 80 (see Figs. 1 and 2) may be secured thereon, this carrying the nozzle exactly similar or in anequivalent manner to the carrying of the nozzle 28, as shown in Fig. 8. On short lines this extra nozzle is not always required, but there are some installations where it is preferred and as before mentioned, it may be modified it so desired. It should also be understood that while I have illustrated a fitting that is a booster and ash intake with the main line of the conveyer extending straight, the fitting may be any type. For example, a fitting similar tion of the construction, othersbeing obvi ous to those skilled in the art.

Having'thus described my invention is obvious that various immaterial. modifications may be made in the same without departing from the spirit of my invention;

hence I do not wish tov be understood as limiting myself fto'theexact form, arrangellO ment, construction and combination of parts herein shown and described oruses menhoned.
